The key element of MirrorMode is that there is an external frontend
that
ensures that all writes are directed to a single server. Otherwise,
there is
no difference.

Should I change the docs for MM? We do writes to a single server to guarantee
writes correct? If they are both the same, should we rename MirrorMode to a different
key word?
We don't use the server URI in the MM example, maybe that section should be totally re-written
as it seems to be confusing users.
Thoughts?

Well, at least maybe some clarification, if a total re-write is too time

consuming. If the difference between the two

has nothing to do with the number of nodes involved, and only whether or
not

there's an external frontend, perhaps they

would be more aptly titled "N-Way Multi-Master" and "Proxied N-Way

Multi-Master".

Absolutely not. The name MirrorMode was specifically chosen to avoid any
association with the concept of multi-master. The purpose of MirrorMode is to
guarantee single-master consistency while providing hot standby.
